Be it known that l, Asensi G. lVILsoN, a citizen of the United States, residing at Vililliinsburg, in the county of Allegheny and State of Pennsylvania, have'invented certain new and useful lniprovementsin Systems of Charging Storage Batteries, of which the following is a speciiication.

My invention relates more particularly to railway signaling systems wherein electric currents are employed as the motive power for operating the translating or o1 her devi-'ses and apparatus in the signaling s teni, and in the present insta-nce it is more portierilarly intended for use in connection with those systems employing storage batteries as the source of current-supply for the trans-' lating or other devices and apparatus used in the signaling system.

l prefer to use the primary source of electric supply an alternating current and to employ means for changing or transforming such alternating current into a unidirectional current. `any suitable transforming device may be used, and in the present instance l have shown one commonly known inthe art as a "rcctiiier" This transforming device is commercially known as an alternatii'ig-curront rectifier,"I and in the present invention it is connected with the mains or feed-Wires on which alternating current of high voltage is impressed, such current being changed or transformed within said rectifier into a unidirectional current and fed to suitable batteries co veniently situated between the rectifier and the signals and Yfrom which current is supplied to the translating or other devices,- apparatus, and tothe railway-signaloperating mechanisms and track-circuits of the signaling system.

One of the objects of the present invention is to provide storage batteries in a railway signaling system and to charge such storage batteries byaunidirectional current obtained from an alternating-current, feed-Wires which may extend from tqhe storage batteries to the ,circuits of the signaling system, and resistai'ices or other devices may be used in any circuit Where it is desired to reduce the voltage or current, or both, supplied from the storage satt-er.

lily invention 'further conteniplat of' suitable transformers having l@ USG primaries and secondaries, a current from the main ieedfvvires being impressed in .the pri- 55 mary and induced in the secondary, whence it `lioivs through proper Wires to the lamps for lightin the railway-signal. Appropri-- ate contro ling-switches are also contemplated for use in connection with my inven- 6o tion, which will be hereinafter fully described. v

In the accompanying drawings, Figure l shows a partialtv perspective and partially dia gramm ati ,al view of a. railway-signal 'and 65 lighting "t embodying my invention, the arrangement and construction therein slifiivvn being particularly adaptable for use where a low voltage on both the si nal and track is desired. Fig. 2 is a simi ar vievr 7o showing a construction and arrangement adaptable for use where a high voltage is desired en tbe signal and a low voltage on the track-circuits of the signaling system. Fig. 3 is a detail. view of two of the batteries 75 shown in Fiyi 2, the charging-switch there- -sed or moved into position to chai e tne other battery.

Sui .iiblc reference characters are employed v 'to designate the various parts on the draw- 8o ings, and where such narts may correspond the same characters will be used.

l will now describe my invention in connection with said drawings, -Whicli illustrate a portion of a. tivo-track railway and some of 85 the parts and appliances included in a signaling system therefor, as Well as the circuits and manner of charging the storage batteries from the main or feed Wires of high alternating voltage and will then describ'` `the man- 9o ner in which the parts and ap: dances and circuits of the signaling syster are supplied With a unidirectional current, finally pointing out the novel features in the claims,

Referring particularly to Fig. 1 of said 95 drawings, A designates the apparatus orK means for transforming an alternating current into a unidirectional current, and, as before mentioned, each means may comprise an alternating-.current rectifier of the type iocabove mentioned, or it may be of any other suitable and approved kind," being herein shown as comprising transformers o and a', suitably supported and located, respectively, one et each side of a rectifyingcell a?. The ing,

usual l connections between the transformers o and einem switch 2t, and then through Wires 7L rand 8 bach to the secondary d. rlhe switches t and t may also be dispensed `with in this instance and the supply to the transformer l) eut oit by. means of the switch 2a. ln this construction and arrangement, and especially Where it is desiredD to provide a high voltage for the motor or electric control of the railway-signal mechanism and a low voltage, on the track-circuits of the signaling system, two sets of batteries are used. 1n

this Way l am enabled to regulate the potential required for the respective batteries so as to suit varying requirements, as Well 'as to minimize in the expenditure of electromagnetic force. Each set of these batteries is arranged in pairs precisely similar to that previously described. 'T he method of charging the batteries is the same in every respect,

. and the charging-switches are arranged soas to shift from one battery in one set to the other battery in the saine set, so as to simultaneously place them in a condition the one to be charged and the other to discharge and supply the signal and traclcircuits- Thecurrcnt for the signal mechanisms after passing om the rectiiier will charge battery s2 r 'honing along the wire 9'?, thence through .cir a and along Wires 11EL 12?/ 13a to plate p, thenc through wire 14 to the positive pole 15C olf' the battery s2, through said battery to the opposite or negative pole 16"', thence through wire 17 a (dotted lines) to contaetl18, through plate p7 and wires 19a 20a 21a, thence through the switch 10a andv Wire L22a back to the rectitying-cell b. In charging the battery s3 the switch will of course be reversed to assume the position shown in Fig. 3, the current ilovving through Wire 9, switch 10, Sac., in the manner just described to and through plate p, thence direct to the positive pole 17@ of the battery s, through the latter to the opposite or negative pole 1S thereof, thence through plate p7 and wires 19 '20a '21a to switch 10a, and finally along wire 22L1 back to rcctitying-cell b. As shown, the battery s3 is out oli` bv the switch and is free to discharge through the Wire 3Q (dottedlines) at positive side of battery, the current ilovving to plate p5, thence through Wires 24 25a to springs `r2 r of a polarized rclay R', thence through Wires 26*1 27a to the home and distant signal mechanisms of the signal Q/ in the usual manner, thence through wires 28a 2Q*Lut to vplate p14, and through Wire 28e (dotted lines) haclif` toI negative side oi battery s3.

he .current vtrom this battery also hows through awire 31a, which is connected to and leads hom the 'Wire '.25d to springs r4 T5 of a polarized relay R2 in circuit with the .upper track section T, as previously described, thence thro ugh wires 32""33a tothe home and distant signalA mechanism of the .igual @j used in connection with and controlling trat 'tic over the track-section T, whence it flows through Wires 34, 35, 36, and 37 to 'Wire :2i-l and back to the negative side of batter;-` s, through the plate p4 and wire 23a.

The traclecircuits ot the signaling system in this form of the invention vare preferably supplied from separate batteries SL of much lower volta-ge, and they are arranged in paires* 'S5 and charged in a similar manner to that just described, the switch 10a, however, being first moved to assume Ithe position shown in dotted lines, Fig. 2, to engage contacts C on wires 38 39, respectively, which lead to the chargiiig-switch for the batteries. The current from the vrectifier B Will llow through the wire 9, switch 10a, 'and Wire 38 to the charging switch, the latter being .moved to connect with one or the other of the batteries` to be char ed, and the'currentA will flow through such attery back to the rectiiier through the Wire 39, switch 10a, and wire 22, as before. The battery s" in this instance is in condition to discharge, and the current from the positive side thereof` will flow through Wire 4() (dotted lines) to and through plate 41, thence through Wire 42 and resistance-10H43 to one arm of apole-changer 4A', thence through Wires 45 4'6 through one rail in the block .e of track-section T to a relay (similar to'rclay Riz) in the track-section in the rear (not/shown) and back through the other rail in said block Z, thencethrough 'wires 47V 48', through the opposite arm of polechanger 44, along wires 49, and through sistance-coil 50, thence through wires 51 52 to plate 53, and finally ,through Wire 54 (dotted lines) back to negative side of battery s4.

The batteries S2 also connect with and energize the relay in the block y to the rear-as, tor example, the relay R, (shown in Fig. 1)M whereby the signal-blades are kept in their normal position, and the current from said batterywill iow through the wires 42 11TL and resistance 43 to one, arin of a polechanger 44a, thence through wire 45 and along one rail oli. the block-section y to wire L16h-,through said vwirefandvrelay lt, thence throug'hwire 47 and along the other rail of trackesection y and through Wires 48 49a to the other' arm of pole-changer 44, whence it lows through Wire 51, resistance 50a, and wire 52 to and through wires 51 52, and finally through plate 53 and wire 54 bach to negative side of battery si.
